After commit f5ff79fd ("dma-mapping: remove CONFIG_DMA_REMAP") there's
a chance of DMA buffer getting allocated via vmalloc(), which messes up
the mmapping code:

> RIP: msc_mmap_fault [intel_th_msu]
> Call Trace:
>  <TASK>
>  __do_fault
>  do_fault
...

Fix this by accounting for vmalloc possibility.

Systems that initiate frequent suspend/resume from userspace
can make the kernel aware by enabling PM_USERSPACE_AUTOSLEEP
config.

This allows for certain sleep-sensitive code (wireguard/rng) to
decide on what preparatory work should be performed (or not) in
their pm_notification callbacks.

This patch was prompted by the discussion at [1] which attempts
to remove CONFIG_ANDROID that currently guards these code paths.

The uacce driver must deal with a possible removal of the parent device
or parent driver module rmmod at any time.

Although uacce_remove(), called on device removal and on driver unbind,
prevents future use of the uacce fops by removing the cdev, fops that
were called before that point may still be running.

Serialize uacce_fops_open() and uacce_remove() with uacce->mutex.
Serialize other fops against uacce_remove() with q->mutex.
Since we need to protect uacce_fops_poll() which gets called on the fast
path, replace uacce->queues_lock with q->mutex to improve scalability.
The other fops are only used during setup.

uacce_queue_is_valid(), checked under q->mutex or uacce->mutex, denotes
whether uacce_remove() has disabled all queues. If that is the case,
don't go any further since the parent device is being removed and
uacce->ops should not be called anymore.

When the target process is busy, incoming oneway transactions are
queued in the async_todo list. If the clients continue sending extra
oneway transactions while the target process is frozen, this queue can
become too large to accommodate new transactions. That's why binder
driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's
helpful to debug the async binder buffer exhausting issue, but the
issue itself isn't solved directly.

In real cases applications are designed to send oneway transactions
repeatedly, delivering updated inforamtion to the target process.
Typical examples are Wi-Fi signal strength and some real time sensor
data. Even if the apps might only care about the lastet information,
all outdated oneway transactions are still accumulated there until the
frozen process is thawed later. For this kind of situations, there's
no existing method to skip those outdated transactions and deliver the
latest one only.

This patch introduces a new transaction flag TF_UPDATE_TXN. To use it,
use apps can set this new flag along with TF_ONE_WAY. When such an
oneway transaction is to be queued into the async_todo list of a frozen
process, binder driver will check if any previous pending transactions
can be superseded by comparing their code, flags and target node. If
such an outdated pending transaction is found, the latest transaction
will supersede that outdated one. This effectively prevents the async
binder buffer running out and saves unnecessary binder read workloads.

Pull cifs client fixes from Steve French:
 "Fixes addressing important multichannel, and reconnect issues.

  Multichannel mounts when the server network interfaces changed, or ip
  addresses changed, uncovered problems, especially in reconnect, but
  the patches for this were held up until recently due to some lock
  conflicts that are now addressed.

  Included in this set of fixes:

   - three fixes relating to multichannel reconnect, dynamically
     adjusting the list of server interfaces to avoid problems during
     reconnect

   - a lock conflict fix related to the above

   - two important fixes for negotiate on secondary channels (null
     netname can unintentionally cause multichannel to be disabled to
     some servers)

   - a reconnect fix (reporting incorrect IP address in some cases)"

* tag '5.19-rc3-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: update cifs_ses::ip_addr after failover
  cifs: avoid deadlocks while updating iface
  cifs: periodically query network interfaces from server
  cifs: during reconnect, update interface if necessary
  cifs: change iface_list from array to sorted linked list
  smb3: use netname when available on secondary channels
  smb3: fix empty netname context on secondary channels

perf already support ignore_missing_thread for -p, but not yet
applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread
for `perf stat -p <pid>`.

Committer notes:

And here is a refresher about the 'ignore_missing_thread' knob, from a
previous patch using it:

  ca800068 ("perf evsel: Enable ignore_missing_thread for pid option")

  ---
    While monitoring a multithread process with pid option, perf sometimes
    may return sys_perf_event_open failure with 3(No such process) if any of
    the process's threads die before we open the event. However, we want
    perf continue monitoring the remaining threads and do not exit with
    error.

When 'perf inject' creates a new file, it reuses the data offset from
the input file. If there has been a change on the size of the header, as
happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
a corrupted output file.

This change adds the function perf_session__data_offset to compute the
data offset based on the current header size, and uses that instead of
the offset from the original input file.
